Feasibility Study On Raw Water Project Of Qingcaosha Water Source In Changjiang Estuary

The project of Qingcaosha water source is one of the significant infrastructure construction projects that have been included in"The Guideline of Shanghai 11th Five-Year Plan of National Economy and Society Development". It greatly contributes to"one-hundred-year strategy"of the development of shanghai water source system, in which the quantity, quality and the safety of Shanghai raw water supply are of concern. This project includes three components: (1) Qingcaosha reservoir; (2) a pipeline system across Changjiang River; and (3) an inland pipeline and pumping station system. These sub-items innovate in techniques with pioneering work. They are all characterized by big investment, high risk, technical difficulty, and pressing rate of progress and so on.In the first chapter, the situation of Shanghai raw water supply was first analyzed from the perspective of planning of city water source system. The second chapter assessed the technical feasibility of these sub-projects. Third chapter evaluated the economic viability of water source construction. The fourth chapter presented risk analysis and management during construction and operation, and eventually led to conclusions and suggestions.
